Checking whether process is running or not

Posted by ArchanGhosh (ArchanGhosh), 20 February 2003
Hi,

I would like to know if there is any command/function i that can help ascertain whether a particular process is currently running on the system or not .

Thanks and Regards,
Archan

That's something that's always very awkward in any language - if you have a look at opertaing systems, you'll often find that they write "pid files" to the disc to tell other processes where they are, for example.   How do you know which particular process it is that you want to check for - by its process id?   By its name?  By whether there's something providing a service on a port? .... I'm afraid there isn't a general answer to the question - please post further telling us how you can identify the process you want to find out about, and I'll let you know if there's an easy way / how I would look at doing it
